True or False: If stack pressures are large, it is best practice to monitor enclosure pressure across the opening during testing.

True or False: If stack pressures are large, it is best practice to monitor enclosure pressure across the opening during testing.

• A. True
• B. False
• C. Only if advised by a supervisor
• D. This practice is not recommended

Answer: (A)

Monitoring enclosure pressure across the opening during testing is considered best practice when stack pressures are large. Large stack pressures can greatly influence the airtightness readings and overall performance of the building envelope. By monitoring the pressure differential across the opening, testers can obtain a more accurate representation of how the enclosure behaves under these conditions. This practice helps in identifying any potential leaks or shortcomings in the air barrier system, allowing for more precise data collection and analysis. This is crucial for ensuring that the building meets the required airtightness standards and for implementing effective remediation strategies if needed. Thus, the statement is true, as it emphasizes the importance of careful monitoring in the presence of significant stack pressures.
